The processes of obtaining, preserving, accumulating and recalling Narcissistic Supply take place in the Pathological Narcissistic Space (PNS). This is an imaginary environment, a comfort zone, invented by the
narcissist. It has clear geographical and physical boundaries: a home, a neighbourhood, a city, a country. The narcissist strives to maximise the amount of Narcissistic Supply that he derives from people within the PNS. There, he seeks admiration, adoration, approval, applause, or, as a minimum: attention. If not fame - then notoriety. If not real achievements - then contrived or imagined ones. If not real distinction - then concocted and forced "uniqueness".
The narcissist's PNS incorporates people whose role is to applaud, admire, adore, approve and attend to the narcissist. Extracting Narcissistic Supply from them calls for emotional and cognitive investments, stability, perseverance, long-term presence, attachment, collaboration, emotional agility, people skills and so on.
